Prader-Willi Syndrome Clinical Trial
Official title:
A Phase 3, Randomized, Double-Blind, Placebo-controlled, Efficacy and Safety Study of Pitolisant Followed by an Open-Label Extension in Patients With Prader-Willi Syndrome
This is a Phase 3, randomized, double-blind, placebo-controlled, multicenter, global clinical study to assess the efficacy and safety of pitolisant in patients living with Prader-Willi syndrome. The primary objective of this study is to evaluate the efficacy of pitolisant in treating excessive daytime sleepiness (EDS) in patients ≥6 years of age with Prader-Willi syndrome. Secondary objectives include assessing the impact of pitolisant on: - Irritable and disruptive behaviors - Hyperphagia - Other behavioral problems including social withdrawal, stereotypic behavior, hyperactivity/noncompliance, and inappropriate speech
The study will consist of an up to 45-day Screening/Baseline Period, a Double-Blind Treatment Period, and an optional Open-Label Extension Period. After completion of all Baseline assessments, patients who meet all eligibility criteria will be randomized 1:1 to receive once daily pitolisant or matching placebo. During the Double-Blind Treatment Period, in-person visits will be at Day 29, Day 57, and Day 77. Patients who do not elect to enter the Open-Label Extension Period will have follow-up visits 15 days and 30 days after the final dose of study drug. During the optional Open-Label Extension Period, in-person visits will be at Day 113, Day 260, and Day 441. Patients will have follow-up visits 15 days and 30 days after the final dose of pitolisant. ;
